Improvement in railway rail-chairs and joints



UNITED STATES PATENT I OFFICEo JOHN M. ORB, OF LEESBUBG, VIRGINIA.'

IMPROVEMENT IN RAILWAY RAIL-CHAIRS AND JOINTS.

Specilication forming part of Letters Patent No. 104,057, dated June 7, 1870.

To all whom it may concern:

Be it known that I, JOHN M. ORR, of Leesburg, in the county of Loudoun and State of Virginia, have invented certain Improvements in Railway Chairs and .Ioints, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to railways; and it consists in a novel construction and arrangement of the chair, iish-bar, and rail, as hereinafter explained.

Figure 1 is a top plan view of the parts complete and in position. Fig. 2 is a cross-section ofthe same on the line x x of Fig. l, with a portion of a car-wheel resting thereon. Figs. 3, et, 5, and 6 areperspective views of the chair and sh-bar detached.

In making my improved railway-j oint I first recess, e, along its outer face, corresponding with the rib n on the inner face of the ange T of the chair, as represented in the drawings, this barF having its opposite side made of a form corresponding to the side of the rail, it having a projection, c, to fit into the cavity between the head and iiange of the rail, as shown in Fig. 2. This bar Fis slightly rounded on its face at each end, and is made of such a width that when placed in the chair alongside of the rails its upper surface shall come iiush with or slightly above the top of the rails, so as tov form abearing for the wheels W as the latter pass over it. As the wheels are made slightly conical, with their smaller ends outward, the bar'should be just enough higher than the rails to compensate for this conical form of the wheels, and it may be made very slightly convex on its upper surface, so that when the wheel arrives at its center and directly opposite the joint in the rails the weight shall be borne almost entirely on the bar F, and thus prevent the battering or wearing of the rails at their ends. This bar F is formed with a couple of-projections or shoulders, h, one at each end, far enough apart to permit them to project down over the ends of the chair C when inserted therein, which thus prevent the bar from being moved endwise after being inserted; or, instead of these shoulders h hooking over the ends of the chair,

`bar F, as shown in Figs. 1 and 2.

If desired, the ordinary bolts may be used to unite the rails R and the bar F, as represented at a, Fig. l; but as the rails and bar are both securely locked in the chair in such a manner that neither'can be. removed except by moving the rail endwise, the bolts may be dispensed with, which will greatly lessen the expense and also the labor of laying the track.

By these means I produce a very strong and durable joint, and lock the railin the chair in such a manner that it cannot be turned over or wrenched loose, and the chair., being very wide, has a large bearing-surface on the sleeper, and can be spiked down and held very securely in place.

Having thus described my invention, what I claim isl. The joint-bar F, provided with the shoulders h, or their equivalents, to hold the same in the chair, substantially as described.

2. The joint-bar F, provided with the shoulders h and longitudinal groove e, in combination with the chair T, having its lip provided with the inwardly-proj ecting rib n, when constructed and arranged to operate in connection with the rail R, as and for the purpose set forth.Y
